For all we know, the bankers allow the Gold prices to rally, to encourage increased production, and encourage the ladies to turn in old jewelry to be molded into Gold Ingots for COMEX contracts consumption. Then they bash the price down and take delivery and STASH it for insurance.
Lets face it. The present Federal Reserve System it totally worn out. Constant problems. Fix or repair daily. Frequent overhaul and rapid depreciation. A new system, a reversal of this one, will have to start from basics. An honest, realistic, practical standardized Gold backed currency monetary system like before 1913.
So they need gold. They have all the responsibility. Its just natural evolution of the system going on.
